Application inea september 7. 1915.

To @ZZ whom z'tmajz/ concern:

Be it known that I, BERNARD BERGMANN, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful improvements inTrough-Flushers, of which the following is a speciiication, referencebeing had therein to the accompanying drawings.

In the operation of drains in floor of bars and counters, and in otherplaces, that are set into-floors and the like and are usually formed oftile or cementitious material, it is desirable to have a controllablewater supply from fittings that do not clog readily, that do notprotrude above the surface and that are readily accessible forinspection and cleaning.

This invention relates to a iiusher adapted for use with'floor drains'orthe like and to an arrangement thereof whereby a substantiallycontinuous extension of a drain bed that does not clogl and that iseasily mounted in position is obtained.

rllhe invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims;

Referring to the drawings, Figure 1 is a plan view of a flusher thatembodies features of the invention; Fig. Q is a transverse verticalvsection of the iiusher in operative position within a Vbed or floor ofcementitious material; Fig. 3 is a longitudinal vertical section throughthe same showing a portion of a gutter or trough to which it isappliedin use; Fig. 4i isa sectional detail taken on or about line IV-IV ofFig. 3.

1n theA drawings anupright inlet barrel 1 has a depending flared endportion 2 into which a valve casing 3 is screwed or otherwise suitablyfitted. rlllhe depending nipple a ofthe casing is adapted to receive apipe or pipe coupling. An annular valve seat 5 in the casing 3 may besealed by a closure 6 that is carried by a valve stem 7, the enlargedandscrewthreaded portion 8 of which is in screwthreaded engagement with thecasing, water passages 2O being provided in the casing at each side oftheenlarged por- Specication of Letters Patent.

tion ofthe stem, all asin the usual construction of valve members, theconstruction of the valve per Se not being a part of this invention, asany type of valve that is oper"- at'ed by aV rotatable stem may be used.

A floor plateof suitable contour having a marginal flange' 9, ispreferably formed integral with the upper end portion ofr the barrel 1,and a suitable annular flange 10 ony the floor plate is arrangedconcentric witlr an opening in the plate through which the valve stem 7passes, said flange being screwthreaded to receive a compressionfnut 11which is adapted to compress a packing 12 within the lflange around thestem and form a tight gland or stufling box through which the stem 7projects A hand wheel 13 or the like below the plane of the rim of theflange 9providesmeans for manipulating the valve.

A transversely arranged upwardlyprojecting hollow boss 141 on the platehas an oblique discharge slot 15 in the front wall thereof that is incommunication through a passage 16 in a downwardly extending hollow bossor connection 17 of the plate with theinterior of the barrel 1. Thecrosssectional contour of the open end portion ofthe floor platecorresponds with the cross sectional contour of the trough or gutter 22formed in the cementitious or other material of the floor 18 or otherpart into which the plate is embedded and anchored by lugs 21 thereon.The direction of flow from the slot 15 is downward across the smoothlyrounded surface 19 of the floor plate which forms an end portion for thetrough or gutter 22.

As a result of this construction a lusher is obtained that forms asubstantially continuous extension of the gutter, trough or the like towhich it isapplied, and the flow from the discharge into said extensionis in such a direction as to prevent lodgment of debris to clog it,while the valve operating parts are below the level of the hoor andthereare no parts projecting above the plane of the upper edge ofthetrough to become injuredand the trough is unobstructed.

Obviously changes in the details of construction may be made withoutdeparting from the spirit of the invention and I do not care to limitmyself to any particular form or arrangement of parts.

What I claim is 1. A flusher comprising a plate having a cross-sectionalform corresponding to the cross-sectional form of the open end of atrough to which it is adapted to be applied, said plate being providedwith a discharge opening adapted to direct fluid into said trough overthe bottom thereof, and means carried by the plate for supplying fluidto be discharged through the discharge opening.

42. The combination with a body of cementitious Vmaterial forming atrough having an open end, of a plate embedded in said body and forminga closed end for the open end of said trough conforming to thecrosssectional end portion thereof, said plate being formed with a fluiddischarge opening arranged to direct water longitudinally1 anddownwardly over the bottom of the trough, and means carried by saidplate for supplying a fluid to said discharge opening.

3. A flusher comprising a plate adapted to be secured at one end ofatrough as a continuation thereof and having a form correspondingthereto, said plate being provided with a fluid discharge openingarranged to discharge :longitudinally and downwardly over the bottom ofsaid plate andtrough, means on the plate forming a fluid passage leadingtosaid discharge opening, and a valve to control said passage.

4. A flusher comprising a concave floor plate having a cross, sectioncorresponding to a trough to which it is to be applied at an open endthereof and formed with a boss having'l a discharge slot in the sidewallthereof, a depending barrel in communication with said slot, a valve inthe barrel, and means for manipulating the valve eX- tending through theioor plate and lying below the plane of the upper marginal portionsthereof.

5. A flusher comprising a floor plate adapted to be secured at the openend of a floor trough to form a continuation thereof and having amarginal flange the upper edge of which' is adapted to lie in the planeof the upper edge of the trough, said plate being formed with anupwardly projecting hollow boss at a distance from the end flange of theplate, said boss being formed with a discharge opening to direct fluiddownwardly and along the bottom of the plate and trough, a memberdepending from the( plate forming a fluid passage discharging throughsaid opening in said boss; a valve in said member, and means foroperating the valve extending through the plate between the end flangethereof and said boss and lying below the plane of the upper edge of themarginal flange of said plate.

6. The combination with a trough of cementitious material, of a floorplate em bedded therein and forming a substantially flush continuationthereof at one end, a barrel depending from the plate, a raised hollowportion of the plate having a transverse slot on the top side incommunication with the interior of the barrel, a valve detachablysecured on the lower portion of the barrel for. regulating the flowtherethrough, and means for manipulating the valve extending through thefloor plate and lying below the plane of the upper margin thereof.

7. A iusher comprising a lloor plate adapted to be secured at the end ofa trough as a flush continuation thereof, a hollow boss transverselydisposed on the plate and provided with a transverse downwardly directedslot in the wall toward the trough endof the plate, a hollow barreldepending from the plate, a hollow boss whose interior forms a channelconnecting the interior of the slotted boss with the barrel, a valvedetachably secured on the lower end of the barrel, and means formanipulating the valve that extends through the floor plate and liesbelow the plane of the upper mar` gins thereof.

8. In a flusher, a floor plate having an open trough end with crosssectional contour corresponding to the trough to which it is to beapplied, a hollow boss formed in the surface of the plate transverselythereto with the upper face at least flush with or below the level ofthe upper margin of the Hoor plate, a barrel depending from the rearportion of the plate, a hollow boss on the lower side of the plateforming communieation between the slotted boss and the barrel, the plateand the bosses and barrel being formed integrally, a valve casingdetachably secured on the lower portion of the barrel, a closurecontrolling the How through the casing, a rotatable member for operatingthe closure extending through the barrel and floor plate, a packinggland on the floor plate engaging around the rotary member, and a handlefor turning the rotary member placed below the plane of the uppermargins of the floor plate.

9. A iusher comprising a smoothly concaved and flanged plate having anopen end the cross section of which corresponds in contour to that of atrough to which the plate is applied, a hollow boss extendingtransversely across the plate and having a transverse slot in the wallsadjacent the trough end of the plate that is downwardly oblique, abarrel depending from the plate behind the transverse boss, a boss onthe lower face of the plate forming a communication between the interiorof the barrel and the interior of the Slotted boss, a valve the plate,and exterior anchoring lugs pro- 10 casing detaohably secured on thelower end jeotng from the plate. l
